A stochastic template bank for gravitational wave searches for precessing neutron-star--black-hole coalescence events

Understand

Gravitational wave searches to date have largely focused on non-precessing systems.

• Including precession effects greatly increases the number of templates to be searched over.
• This leads to a corresponding increase in the computational cost and can increase the false alarm rate of a realistic search.
• On the other hand, there might be astrophysical systems that are entirely missed by non-precessing searches.
